Is a hatred for cilantro irreversible?

Julia Child is famously quoted as stating that as far as
cilantro goes, the best thing to do is "just pick it out and throw
it on the floor." There is no question that most people are very
firm on their attitude towards cilantro - they either love it or
hate it. A few years ago, noted food scientist Harold McGee claimed
that this prefernce was, in fact, genetic based and there really
wasn't a lot that could be done to change it. The Salt
recently reviewed the question and found the
story to be more nuanced.

As they write, "Two studies published this week link the
aversion for cilantro with specific genes involved in taste and
smell. But, just like the flavors of the herb itself, the findings
are nuanced: The genes appear to influence our opinion of cilantro
but probably not as much as we initially thought." The problem
appears to be especially related to odor - people who dislike
cilantro think it smells and tastes like soap.
